how to make SD card as ram?

Use a SWAP file: The excellent free Swapper utility in the Android Market makes this easy.  Simply install Swapper on your rooted phone, run it and hit the "Swap ON" button.  One caveat, you need a fast SD card for this to work.  I initially tried Swapper with regular speed 2 GB Kingston SD card that came with the phone and all it did was slow the phone down and made it unstable.  I replaced the card with a (shameless affiliate link) $10 Transcend Class 6, 4GB card from Amazon and the difference was amazing.  With the Class 6 card, enabling swap made my phone faster than stock and at least as stable and went a long way toward solving the browser cache issues.  While Swapper works pretty well out of the box, you can get even better performance by tweaking the settings a bit.  Everyone has different opinions on the ideal swap configuration. Based on trial and error, I found that using a 64 MB swap partition and a "Swappiness" setting of 60 seems to work best for me.  Setting up a swap partition requires some extra steps (Part of the Apps2SD setup,  explained here ).  If that sounds like too much trouble. you can get nearly as good results with a 64 MB swap file instead of a partition.

I had an error once.  Wifi couldn't turn on.  Restarted phone and it was ok.

Also had a sudden shutdown of the phone.  Took it out of my pocket and it's off.  Couldn't turn it back on using the power key.  Took out battery, re-inserted, and it was ok.

Used for 2 weeks.

SP selling on eBay if you don't mind waiting.  Pretty cheap.

Noticed my Samsung charger, the connector to the phone has 1 pin missing.  Been charging with it all this while.  Are chargers under warranty?  Where to go to claim?

guys, this "sleep death issue" is a hardware issue!

u better should run and change your phone, as long as you can...

google for "captivate shutdown issue" exact the same known problem.
